Anthurium plant named ‘ANTHIOWIR’

ABSTRACT

A new and distinct variety of  Anthurium  plant named ‘ANTHIOWIR’ particularly distinguished by having a characteristic glossy, purple spathe and a deep purple spadix, elliptical cordate and dark green leaves with dark red primary veins, continuously flowering throughout the year, little shoots creating an open plant habit with a height of 55 cm to 65 cm, is disclosed.

Genus and species: Anthurium andreanum L.

Variety denomination: ‘ANTHIOWIR’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andreanum L., and hereinafter referred to by the variety name ‘ANTHIOWIR’. The new variety originated from a hybridization made in July 2000 in Bleiswijk, The Netherlands. The female parent was a pink-purple Anthurium pot plant designated ‘372-01’ (unpatented), and the male parent was a purple Anthurium plant designated ‘2305-01’ (unpatented).

A single plant was selected in August 2002 and has been asexually reproduced repeatedly by meristem tissue culture in Bleiswijk, The Netherlands over a seven-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in the European Union on Jun. 10, 2014 and in China on Jan. 29, 2015. ‘ANTHIOWIR’ has not been made publicly available or sold anywhere in the world more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands:

-   -   1) Purple and glossy spathe;     -   2) Deep purple spadix;     -   3) Brown-red peduncle;     -   4) Elliptical cordate leaf with dark red veins; and     -   5) Dark green foliage.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 58-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in June 2015.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHIOWIR’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 58-week old plants which were planted from tissue culture in 17-centimeter pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in June 2015. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).
